DUIVIPING-CAR.

Original application filed November 14, 1910, Serial No. 592,167.

Specification of Letters Patent.

9, 1912. Serial No. 714,179.

To all whom it may concern:

Be it known that I, HOWARD GREEK, Jr., a citizen of the United States, residing at Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Dumping-Cars, of which the following is a specification.

This application is a division of my original application, Serial No. 592,167, filed in the United States Patent Office on or about November l lth, 1910, and to which application reference may be had for an understanding of the construction and operation of the parts not fully described herein.

This invention relates to improvements in dumping cars, in which the wheel journal boxes are located on the inside of the wheels and in position so that they will not engage any obstructions and so that they will not be embedded in the material dumped to the side of the car, and one of the objects of the invention is to provide an improved construction of car body pedestal which will facilitate the dumping of the car and which, with the arrangement of the inside wheel journal boxes, will increase to a maximum the angle of dump of the car.

To the attainment of these ends and the accomplishment of other new and useful objects, as will appear, the invention consists in the features of novelty, in substantially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed, and shown in the accompanying drawings illustrating an embodiment of the invention, and in which- Figure l is a top plan view of an improved car truck constructed in accordance with the principles of this invention. Fig. 2 is an end elevation of a car constructed in accordance with the principles of this invention, showing the car body in position to receive a load. Fig. 3 is a detail view partly in elevation and partly in section, showing the bumper on the car bolster and the bumper plate which is secured to the bottom of the car body, the latter being in section. Fig. l is an enlarged detail view, partly in elevation, partly in section, and partly broken away, and with parts omitted, showing a car bolster and pedestal constructed in accordance with the principles of this invention. Fig. 5 is an enlarged side elevation of the car body pedestal, showing parts of the support and car body in section. Fig. 6 is an end elevation of Fig. 5, showing a portlon of the car body in section. Fig. 7 is a detail sectional view on line 7-7 of Fig. 6. Referring more particularly to the drawlngs, and in the present exemplification of this invention, the numeral designates the arch bars forming the sides of the truck which support the journals 21 for the axles 22 of the wheels 23. These journals 21 are located on the inside of the wheels of the truck so that there will be no projection extending beyond the outer faces of the wheels. The springs 24 of the truck bolster 25 (see particularly Fig. 4) rest upon the spring seat 26 and the bolster rests upon the top of these springs in the ordinary and usual manner, to be guided by the bars or columns 27. The truck bolster is of any desired construction, but is preferably of channel iron formation having a center plate 28 secured thereto and which center plate is provided with the usual opening for the king pin. The usual truck side bearings 29 are provided on the bolster 25 adjacent the ends thereof.

The car body 80 is supported by the sills 31 by means of pedestals, each comprising a supporting section 32 which latter rests upon the top of the sill members 31 and are secured thereto in any suitable manner, preferably by means of fastening devices 33 in the form of bolts or the like, which pass through the base of the pedestal and a flange on the sill members. Each of the pedestals may also be provided with a projecting ear or rib 3-1: depending below the lower face of the base thereof and inside of the sill members 31 to engage the faces thereof to assist in holding the pedestal against lateral displacement with respect to the sill members.

Supporting section 32 of the pedestal may be of any desired height and is provided at its upper end with a recessed portion 35 to form upwardly projecting spaced flanges 36 and these flanges are each provided with a centrally disposed recess 37 opening through the tops of the flanges. The bottom of the recesses 37 terminate in substantiallv the same plane as the bottom of the recessed portion 35. The bottom of the recesses 35 between the flanges 36 is further provided with recesses 38 extending below the bottom 35 to form projections 39, which latter are ed to receive a web or flange 41 on an oscillating section 42 of the pedestal. This section 42 is secured to the bottom 30 of the car in any suitable manner, preferably by being secured to the angle truss bar 43 between the flanges 44 of the bar. The section 42 of the pedestal is provided with laterally projecting portions 45 which are of cylindrical construction to form trunnions. These trunnic-ns 45 are adapted to rest upon the bottoms of the recesses 37 in the flanges 36 and are of a diameter somewhat smaller than the recesses, so that the oscillating section 42 may be rocked upon the supporting section 32, the trunnions 45 rotated and rolling in the recesses 37 to permit such oscillation. These trunnions 45 are preferably centrally disposed with respect to the edges of the web 41.' Shoulders 46 are provided on the section 42 which extend over and are normally spaced above the respective reccsses 38 in the bottom. of the recess 35, when the car body 30 is held in a substantially horizontal position, but when the car body is rocked on the trunnicns 45 to oscillate the secticn 42, one pair of shoulders will be lowered toward the respective recesses 38, while the car body is rocking about the trunnion 45. As this rocking movement is imparted to the car body, the trunnion will travel toward the wall of the recess 37 on the side toward which the car is being dumped. By the time the trunnicns 45 reach a position in close proximity to the walls of the recess 37, the shoulders 46 which are being lowered will be moved in close proximity to the recesses 38. This mctirn will be imparted to the car body by throwing the latter out of balance and by the time the shoulders 46 enter the recesses 38, the inertia of the car body will complete the dumping, and the shoulders or projections 39 will hold the parts against displacement. In order to provide an additional means for preventing the inertia caused by the dumping movement of the car body from throwing the car body too far over to the side, which would cause disengagement of the parts, the web 41 is provided with a slot or opening 41 and a pin or fastening device 41 is provided which extends through the walls of the pedestal and also through the slot 41 This pin or fastening bolt is held against longitudinal displacement in any suitable manner and for this purpose the ends of the bolt or pin may be headed or may be threaded to receive nuts. The slot 41- is curved or struck on an are so that the pin 41 will not interfere with the free rocking or dumping movement of the car body, as will be understood. After the car has been dumped, the car body 30 may be swung aboutthe trunnio-ns 45 in the opposite direction until it assumes a position to be again loaded. Cars of this general type are generally loaded with the weight on one side, that is, on the side to which the car is to be dumped, and are held against accidental dumping by means of the anchor chains 47 which latter are secured by one of their extremities to the car body and by their other extremities to the truck. The anchor chains, however, and the manner in which they are secured to the car truck form no part of the present invention, but constitute a portion of the sub ect matter of another application. The web 41 is provided for maintaining the oscillating sections 42 against lateral displacement with respect to the supporting section 32 when the car body is in motion or when a sudden movement is imparted to the car trucks. Any number of these pedestals may be employed according to the size and ca pacity of the car and are of such height that when the car is dumped the maximum angle of dump will be obtained and by the provision of the inside truck journals, this angle of dump will be substantially 49 degrees, or several degrees greater than the maximum angle of dump heretofore obtained in cars of this character. It will also be apparent that by the arrangement of the journals inside of the wheels, the journal boxes will not be embedded or buried in the material dumped from the car, which latter would form obstructions to the advancement of the car and through which the journal boxes would have to be moved before the car could be advanced or the material dumped would have to be removed from around the journal boxes in order to clear the latter. 3

The bodv bolster is preferably constructed with a base designated generally by the reference numeral 48 having arms or portions 49 which terminate short of each other, as shown more clearly in Fig. 4, and a top member 50 which is arched, as shown, so that the bodv bolster will be of substantially triangular formation. The sills 31 of the car project into the space between adjacent extremities of the arms 49 of the bolster and the upper member 50 arches over the sill members, and the arch member is of a height to extend for some distance above the base of the edestal. The free extremity of each arm 49 is secured to the sills 81 in any suitable manner, preferably by fastening devices 51 passing through the sill members and flanged portions of the arms, and a center plate 51 having a king pin guide 52 is secured to the arms across the sills and below the latter. The guide 52 in the center plate 51 registers with the opening in the center plate 28 of the truck bolster 25 and the king pin 53 is passed through the guide 52 and the opening in the plate 28. If desired, additional arms 52 may be provided, which extend from the inner face of the arched member and engage the sill members 31, and these arms may be secured to the sill members by fastening devices similar tothe fastening devices 51. With this improved construction of body bolster, it will be apparent that the maximum strength will be obtained from a given amount of material, and by extending the arched member for some distance above the base of the pedestals and over the sill memhere, all tendency of the parts to twist and thereby Wrench parts will be overcome. T he body bolsters are provided with sockets (see Fig. at) for the reception of cushions or bumpers 55, and the sockets 54 are provided with apertures 56 opening through the bottom thereof and through which apertures any water which may have found its way into the recesses may be discharged. The side bearings 29 on the truck bolster 25 for the body bolster 50 are also located Within the planes of the outer faces of the wheels of the truck. With the bearings thus arranged and with the journals 21 on the inside of the wheels, when the body is brought into engagement with one or the other of the bearings 29, the stress thus exerted on one end of the truck bolster 25 will tend to force the opposite side of the truck clownwardly, and thereby maintain the wheels of the truck on. the opposite side of the car into engagement with the track.

Bumper plates 57 may be provided if desired and when provided may be secured to the bottom of the car body 30 so that they will engage the bumpers when the car is dumped.
